Mine was a 2000. I spent a day in a dyno room tuning out the very minor problem and tweaking top end power. We confirmed the slight lean spot using the dyno, and added fuel. It really was tiny though, and maybe I just got lucky to occasionally want the throttle and RPM at just exactly the place that makes it noticeable. Either way though, it's not something I would have spent money to fix at all. The dyno day and the programmer were free, so they could use my bike for testing.
